Everything About Allergy

Certain insects can cause allergic reactions with their venom, such as bees, wasps and fire ants. Proteins in the venom causes the allergic reaction in humans. People who are not allergic to the venom only develop skin redness, itching, swelling and mild pain on the area of the insect bite. Household treatment such as applying ice on the area is enough.

People that are allergic to the venom may manifest a serious reaction called anaphylactic reaction, where one experiences difficulty breathing, or may lose consciousness. But this reaction occurs on the second or subsequent sting. The first sting usually result to a local reaction, where the skin swells and becomes itchy or painful.

Asthma is an allergic reaction to substances, and may manifest through the lungs where the patient experiences difficulty in breathing. It may also be in the form of allergic rhinitis, where an attack of sneezes occurs. Asthma may also manifest in the skin, which is less dangerous than a lung asthma, but have similar effects – swelling.

Asthma is also hereditary – it is passed on through the family blood line. It is also possible for siblings to have the condition all at the same time. It is likely for children of “asthmatics” to manifest one of the three conditions mentioned above.
